The ACOMP Basic Example shows the simplest way to use ACOMP driver and help user with a quick start.In this example, user should indicate an input channel to capture a voltage signal (can be controlled by user) as the ACOMP's negative channel input. On the postive side, the internal voltage ladder is used to generate the fixed voltage abouthalf value of reference voltage.When running the project, change the input voltage of user-defined channel, then the comparator's output would changebetween logic one and zero when the user's voltage crosses the internal ladder's output. The endless loop in main() functionwould detect the logic value of comparator's output, and change the LED. The LED would be turned on when the compareoutput is logic one, or turned off when zero.

The ACOMP Interrupt Example shows how to use interrupt with ACOMP driver.In this example, user should indicate an input channel to capture a voltage signal (can be controlled by user) as the ACOMP's negative channel input. On the postive side, the internal voltage ladder is used to generate the fixed voltage abouthalf value of reference voltage.When running the project, change the input voltage of user-defined channel, then the comparator's output would changebetween logic one and zero when the user-defined channel's voltage crosses the internal ladder's output. The change ofcomparator's output would generate the falling and rising edge events with their interrupts enabled. When any ACOMP interrupt happens, the ACOMP's ISR would turn on/off the LED light.

The CRC Example project is a demonstration program that uses the KSDK software to generate checksumsfor an ASCII string. Several CRC protocols are implemented using the CRC driver API.

The HelloWorld demo prints the "Hello World" string to the terminal using the SDK UART drivers and repeat what user input. The purpose of this demo is to show how to use the UART, and to provide a simple project for debugging and further development.

The IAP project is a simple demonstration program of the SDK IAP driver. It reads part id, boot code version, unique id and reinvoke ISP. A message a printed on the UART terminal as various bascial iap operations are performed.

The IAP Flash project is a simple demonstration program of the SDK IAP driver. It erases and programs a portion of on-chip flash memory. A message a printed on the UART terminal as various operations on flash memory are performed.

The LED Blinky demo application provides a sanity check for the new SDK build environments and board bring up. The LED Blinky demo uses the systick interrupt to realize the function of timing delay. The example takes turns to shine the LED. The purpose of this demo is to provide a simple project for debugging and further development.

The i2c_interrupt_b2b_transfer_master example shows how to use i2c driver as master to do board to board transfer with interrupt:In this example, one i2c instance as master and another i2c instance on the other board as slave. Master sends a piece of data to slave, and receive a piece of data from slave. This example checks if the data received from slave is correct.

The i2c_interrupt_b2b_transfer_slave example shows how to use i2c driver as slave to do board to board transfer with interrupt:In this example, one i2c instance as slave and another i2c instance on the other board as master. Master sends a piece of data to slave, and receive a piece of data from slave. This example checks if the data received from slave is correct.

The i2c_polling_b2b_master example shows how to use i2c driver as master to do board to board transfer using polling method:In this example, one i2c instance as master and another i2c instance on the other board as slave. Master sends a piece of data to slave, and receive a piece of data from slave. This example checks if the data received from slave is correct.
